The AEO Visibility Index
How ChatGPT, Claude, Perplexity, and Gemini cite the brands buyers actually look up.
Live Mention Scores across the four major AI engines, ranked. Each score is a 0-to-100 index of how often the engine cites the brand when a buyer asks the questions that close deals. Updated daily. Computed by Mentioned AI.

How the score works
Every brand on this index tracks a set of buyer-purchase prompts daily across the four major AI engines. The Mention Score is the share of those prompts where the engine cited the brand by name or domain. 100 means the brand was cited on every tracked prompt this morning; 0 means none. Δ vs yesterday shows day-over-day movement.
The index is opt-in · brands appear only after enabling their public Mention Score page from inside Mentioned AI. Comparison is honest by construction · every brand on the list runs the same prompt set against the same engines on the same daily cadence.
